The Athasaia are Ananasi that have been born from the union of two other Ananasi. When an Athasaia is conceived, he is taken to an Umbral realm, where they are sheltered by the elder Ananasi. In order to awaken, an Athasaia need the blood of at least five men. Some say they will dwell within the Umbra until the time has come to free Ananasa and the Apocalypse has begun.
Athasaia have only one form, the Pithus, and invoke the Delirium in supernaturals in a similar way ordinary Fera invoke it among mortals. Fanatically loyal to their queen, they wait for the time to strike against the Pattern Web and free Ananasa from her opal prison.
